Window or door frame profile or the like



July 23, 1968 H. PASCHE WINDOW OR DOOR FRAME PROFILE OR THE LIKE Fig. 1

Filed April 8, 1966 Fig 5 United States Patent 7 Claims. cl. 52-403 ABSTRACT OF THE DISCLOSURE A window or door frame profile consisting of a metallic core coated with a formed thermoplastic material having projections defined thereon. A metallic reinforcing member is interposed between window pane structure and the thermoplastic coating, and the pane retaining means is defined directly upon the reinforcing element.

Such window and door frame profiles, respectively, provided with a profile configuration still to be described, usually have riveted or screwed thereto at certain spaces metal angles on which, for instance, the window pane to be framed abuts by its butt ends. In this manner, the coating consisting of thermoplastic synthetic material is not only protected from cuts but the elastic projections serving as an abutment for the window panes are relieved at the same time.

After a window pane, for instance, has been fitted in the window frame profile thus prepared, usually, the putty bed is introduced and finally a glazing profile fitted, supporting the window pane by its backside. The glazing profile is screwed or pasted in turn to the frame profile. However, it has also become known already to screw or rivet onto the frame profiles, springs or snapping ledges in such a manner that they only need snap the glazing profile into place in order to support the window panes or the like at the back side.

However, it has now been found that bores for the rivet or screws are very disadvantageous because they not only weaken the frame profile but also create the danger that rain or moisture may intrude in the frame profile, which may in the course of time destroy the carrier profile made of metal.

The invention is based on the problem of providing a window or door frame profile, respectively, in connection with which the arrangement of any bores may be dispensed with, in which in addition care is taken that the projections otherwise serving only as abutments to support the window panes, for instance, at the same time may be used as abutments at the counter profile, namely at the sash frame. The latter feature is of extreme importancebecause it is possible in this way to make all types of windows with only two frame profiles.

In accordance with the invention, this problem is solved in that the projections are capable of being reinforced by a reinforcing profile adapted to be placed therein from the outside.

The reinforcing profile adapted to be placed in the frame profile in this manner still serves another function. It is known that the coating consisting of thermoplastic material and provided with the above projections generally must be made of soft PVC, however, the associated glazing profilein correspondence with the function it is to fulfil--must be made of hard PVC. But now, it is always objectionable to arrange a soft PVC in direct contact with a hard PVC, because the danger of a socalled plasticizer migration then will be imminent, that means that the glazing profile made of hard PVC will Withdraw a certain amount of plasticizer from the coat- 3,393,486 Patented July 23, 1968 ing made of the soft PVC, which will then render also the glazing profile soft or excessively elastic, respectively, so that it will no longer be able to fulfil its intended function.

This danger is encountered by the reinforcing profile which is adapted to be placed in the frame profile and which preferably consists of aluminum, because the reinforcing profile is effective as an insulation between the frame profile or the coating, respectively, and the glazing profile. For this reason, provision is made in accordance with another feature of the invention, to have the reinforcing profile cover the entire face of the frame profile facing the window panes, the insulating glass elements, the structural plates or the like.

In a further development of the invention, the reinforcing profile is provided with supporting surfaces to block the window panes, insulating elements, structural plates or the like, in which suitably the reinforcing profile to effect attachment with no rivets and no screws, engages within rests and is supported against straight or undercut projections. Provision has also been made for the glazing profile to be provided with webs at that side thereof facing the frame profile, which webs are cooperating with rests arranged at the reinforcing profile, undercuts or slots. The arrangement in accordance with the invention secures that the projections of the thermoplastic coatings for the window panes, the insulating glass elements, structural plates or the like to abut thereon, are made essentially weaker so that material may be saved in manufacture and, therefore, will be sufiiciently elastic as an abutment for the counter profile.

The drawings show the invention in several examples of embodiments in a cross sectional view, namely a frame profile glazed with window panes.

In the drawings:

FIG. 1 shows a frame profile with insulating glass window panes,

FIG. 2 shows a simply glazed frame profile in contact with the counter frame (sash),

FIG. 3 shows a frame profile of smaller dimensions and in another embodiment glazed with insulating glass,

FIG. 4 is a simply glazed frame profile according to FIG. 3,

FIG. 5 is a schematic elevational view of an assembled frame formed in accordance with the invention.

In all embodiments, the window panes 1 are shown which are retained by the frame profiles 2 in a manner still to be described in more detail. The frame profiles 2 as well as the counter profile 4 serving as a sash and shown in FIG. 2, both consist of a hollow metal profile 5 tubularly coated with a coating 7 consisting of thermoplastic synthetic material, for instance soft PVC.

The coating 7 completely surrounding the metal profile is provided with projections 8 and 10, the ones designated 8 of which are provided with a sealing tongue 11 in a manner known per se. This projection 8 provided with the sealing tongue normally serves to seal the frame profile 2, insofar as the latter one, as shown in FIG. 2, abuts against the counter profile 4. This sealing tongue, however, is alloted another function when the frame profile 2 according to the invention serves as a holding device for the window pane 1; it lies around the vertical leg of the reinforcing profile 12 and prevents the abutment 8 from being pressed outwardly by the pressure of the glass pane, which will now be described in the following with the aid of FIG.1.

In accordance with FIG. 1, a reinforcing profile 12 preferably consisting of aluminum is provided which is placed in the frame profile 2 in such a manner that the one lateral edge of the reinforcing profile may snap into the angle formed between the projection 8 and the sealing tongue 11 and the other lateral edge of the reinforcing profile 12 with the wider profiles 2 according to FIGS. 1 and 2, may snap for instance into an oblique undercut provided in the frame profile 2. The latter is formed by the already mentioned projection 10.

The reinforcing profile 12 is in addition provided with supporting surfaces 14 on which the window panes 1 are supported in connection with carrier blocks 15.

A glazing profile 17 provided with webs 20 may snappingly engage beneath the one of these supporting surfaces 14 and the angle of the reinforcing profile 12 formed as an oblique undercut, said glazing profile preferably consisting of hard PVC. as soon as the glazing profile has been brought into place, the space remaining between the pane or panes 1, respectively, on the one hand and the glazing profile 17 is filled with putty 18 in an injection process as will be seen from FIG. 1. The putty bed between the pane or panes 1, respectively, and the projections suitably will be brought into place before the pane is arranged therein.

As will be seen from the examples of embodiment of the invention as described and shown in the drawing, it is now possible to design the frame profiles 2 and 4 coated with a coating consisting of soft or elastic synthetic material in such a manner that the projections 8 provided with sealing tongues 11 may at the same time be used as an abutment against the counter profile 4 and the sash frame, respectively, in which it is absolutely safely guaranteed that no moisture can reach the interior of the frame or the counter profile 2, 4 respectively.

FIG. is a schematic elevational view of an assembled frame formed in accordance with the invention. It is composed of four profile lengths the ends of which are cut on a miter cut as shown at 13. In both ends of two profile lengths to be connected with each other, a knee member 22 is inserted in such a manner that it fiushly fits in the hollow cross sectional area of both profiles. Thereupon, the coatings of both profile lengths are connected by bonding, said coatings consisting of plastic material.

The glazing profile 17 of the embodiment shown in FIGS. 1 and 2 is provided with two flanges or webs (vanes 20). Both the webs (vanes) are provided with projections (dents) 19, 21 facing each other and directed outwardly.

The two supporting surfaces 14 are provided with indentations 9 directed towards the ledge 10. The ledge is provided with an undercut indentation 16 which faces towards the ledge 8. A correspondinggly undercut flange of the reinforcing profile 12 engages within the said indentation 16. FIG. 1 shows the embodiment suited for an insulating window provided with two panes. The glazing profile 17 is formed correspondingly narrow. The dent 19 resiliently engages within the corresponding indentation 9 of the one supporting surface 14, and the dent 21 engages within the undercut portion of the flange of the reinforcing profile 12. The same results for the single window with the only difference that the dent 19 of the correspondingly broader designed glazing profile 17 engages within the indentation 9 of the other supporting surface 14.

With the embodiment according to FIGS. 3 and 4, the reinforcing profile 12 is provided with two grooves 3 spaced from each other. The one or other of these grooves may have a flange of the glazing profile 17 engaging therein.
